Answer:
P₂ = 252 W
Explanation:
The electrical power is
P = V I
The potential difference is
V = I R
I = V / R
Let's replace
P = V² / R
Let's use the given values to calculate the resistance of the bulb
R = V² / P
R = 120²/75
R = 192 ohm
This resistance value does not depend on the applied voltage, so it is constant
Let's calculate the power in Europe
P₂ = V₂² / R
P₂ = 220²/192
P₂ = 252 W
the bulb dissipates much more power
